.Illinoisr have invented, a certain new and usefullinprovementinzMailing-Folders, of

which the followin is a specification.

inore. particularly mailing folders or inserts 1e.) by means ofspringing the main leaf is made ernployed for advertising purposes,which to apparently show action, on a picture printed thereon, and whichpossesses a pecullarly. securelocking arrangement directly at the laceof action in the picture. a

.L to 13 inclusive, the folder consists of three leaves, the main leafA, andjthej adjoining leaves 13 and G. The folder may consist of "moreleaves if desired. The leaf B hasa slit B, and the leaf G. has aslit C,in such position as regards the folds B. and C? that when 35 folded thetongue 0 formed bythe slit (3 on leaf C, will fit into. slit B on leafB, thus loikmg e T e eafi B is of a length 2 transverse to the folds Band C sufficiently 7 less than leaf A, to allow springing the leaf on Athe proper distance to operate the lock and cause apparent action onpictures 0, "and 13*. It is preferable to. have leafv A. of

a'length transverse to the iolds B and'jC so that the'edgeB ofleaf Bwhenin con- 96 tact with fold G just prevents the folder from unlocking. Theslit G maybe either generally curved or channel shaped with the ero'wnof the curve or channel toward the adjacent fold C while slit B maybeeither 100 straight or curved as may be exigent so that p in lockin thefolder; the tongue into slit slideswhen. in the efolder.

1 in a direction op osite to the direction of the leaves B and act 0funfolding, thus securin an 'excep- .tionally firm and novel lock for atV A picture C may be painted, printed pasted or stamped overo'r-edjacent to slit C j and another picture B relatingto said pic-o aslight reciprocal pressure on-folds B and causes the pictures B and C towork in conjunction either to indicate action or entirely change.

In the forms shown in Figs. and 16 the folder consists of two leaves,the main leaf C and the narrower adjoining leaf B,

the leaf C having slit C and the leaf B slit B Pictures, one on eachsurface of the open folder or one on but one surface, may be printed,painted, pasted or stamped directly over or adjacent said slits, and themutual operation of said slits and pictures are exactly as hereinbeforedescribed in the multi-leaved folder.

Operation: Take open folder of the forms shown in Figs. 1 to 9inclusive, fold on the folds B and C which are usually parallel to eachother and transverse to the open ends of the folder, so that leaf 0 isin front of leaf B. Where the changeable picture is used,'fold so thatthe pictures B*-and C face the outside of the'folder. Now bend tongue 0?toward the inside of the folder so that it will slip into slit Bstraightenin the tongue C to the same plane as leaf after insertion ismade, thus effectively lockl ing the folder. In the open folder of theforms shown in Figs. 10 to 13 inclusive, fold "so that leaf B is infront of leaf G. Then tongue C should be bent toward the outside of thefolder so that it will slip into slit B on leaf B, after which thetongue is straightened to'the same plane as leaf G, thussecuring thefolder. The folder is just as securely locked in' either method. Wherepictures are used in connection with the lock,

they will usually have reference to the printed or written. mattercontained on the folder. To operate the picture and open the folder ofthe forms shown in Figs. 1 to 13 'inclusive,dplace the thumb of the handalong 1 one close fingers on the far 0 posite edge and press edge of thefolder and the four slowly together untl leaf A is sprung 1n theposition shown inv Fig. 2. In the open folder of the form shown in Figs.15 and 17, fold on the fold B so thatleaf Bis in front of leaf C. Themethod ofclosing the folder and the operation of. the lock, and picture,areexactly as hereinbefore described for the multi-leavcd folder.

It will be seen that a device embod ing this invention has greatadvantages irst, it will remain securely closed in the mail;

. second, on account of the-changeable picture .it will be saved andshown to others, thereby .pasters to securely close the folder; fifth,its

simplicity of manufacture; sixth, its simplicity of operation; seventh,it can be used as a novelty with or without advertising matter;eighth,it can be used as an insert into an envelop.

What I claim as new and wish to secure by Letters Patent is v 1. Afolder having a main leaf which is adjoined on two opposite sides byleaves,

the adjoining leaves being of a width transverse to the folds less thanthat of the main leaf, one leaf of which has agenerally channel or archshaped slit forming a tongue,

the crown of said slit being toward the adjacent fold, another leafhaving a slit designed to receive said tongue in'a direction opposite tothe action of the leaves in opening said folder, forming a lock for thefolder, the narrower adjoining leaves persaid picturedesigned and placedso as to apparently move, disappear, or change when operating the lock.

3. A folder having two or more leaves, one end leaf of which has agenerally channel or arch shaped slit forming a tongue, the crownof-said slit being toward the adjacent fold, another leaf having a slitdesigned to receivesaid tongue, both slits mutually forming a lock, andpictures directly relating to each other, imprinted directly overoradjacent each slit, said pictures designed and placed so as toapparently create action, disappearor change when operating the lock. 4.A folder having two or more leaves,

.one leaf of which has a generally channel or arch shaped slit forming atongue, the crown of said slit being toward the adjacent fold, thetongue to be used as one member of the folders lock, another leaf beingwider between the folds than any of the others, permitting the foldededges of the latter mentioned leaf to be forced toward each other, forthe purpose of unlocking the folder. x
